How it works

Complete the job in three clear steps

  1. Add XML markup to the private browser workspace.
  2. Choose the available settings and create validated formatted or compact XML.
  3. Review the result, then copy or download it before leaving the page.

Important

Check the result before relying on it

Review generated output before using it in production. Formatters and converters can validate structure, but they cannot understand every application-specific rule or guarantee that transformed content has the intended meaning.

Practical details

What this Lucaden tool does

The validator uses the browser XML parser to catch malformed tags and then applies indentation without evaluating external entities. It is suitable for API payloads, feeds, configuration, and document fragments.

Lucaden performs this task in the browser so the source stays under your control. The result is created only after you request it, and nothing is saved to a Lucaden account by this tool.

Questions

About this tool

Does this resolve external entities?

No. The browser parser works on the supplied string and this tool does not fetch referenced resources.

Will mixed text content format perfectly?

Mixed inline text and nested tags can be sensitive to whitespace. Review formatted output before using it in a whitespace-significant system.
